Impact of the Channel Count on the Nonlinear Tolerance in Coherently-detected POLMUX-QPSK modulation
Coherent communications Fiber optics communications
2011/5/26
GPU-based transmission simulations with different channel counts (1~81) are used to determine the minimum required channel number for correctly simulating fiber nonlinearities that impact 40G/100G CP-...
Cycle Slip Mitigation in POLMUX-QPSK Modulation
Cycle Slip Mitigation POLMUX-QPSK Modulation
2011/5/20
We demonstrate a pilot-symbol assisted joint polarization carrier phase estimation technique that detects cycle slip and avoid error propagation. Coherent detection without differential coding is feas...
